Ampeg® B-15N Bass Amplifier
The iconic bass amp sound of the ’60s and ’70s, exclusively for UAD-2 and Apollo.
The Ampeg B-15 bass amp defined the sound of recorded electric bass. From Motown sides with James Jamerson to classic Stax records with Donald “Duck” Dunn, this 30-watt, 1x15, all-tube brute oozes character — delivering a warm and fat fundamental note that laid the foundation for ’60s and ’70s rock, funk, and soul.
Developed by Brainworx, the Ampeg B-15N Bass Amplifier plug-in perfectly emulates the circuitry, tone stack, and iconic thump of Ampeg’s limited-edition Heritage B-15N bass amp — exclusively for UAD-2 hardware and

Take A Listen
The Sound of Giants
The Ampeg B-15N Bass Amplifier plug-in flawlessly captures the original hardware’s dual 6L6-powered circuit as well as its simple, ultra-musical two-band Baxandall EQ. Simply use the Volume control to dial in rich, smoky tones, perfect for jazz and soul, or inch the Volume up for a fat guttural growl that teams with harmonics and character.
Two Channels, Tons of Tones
An evolution of the classic B-15 recipe, the B-15N sports two channels — 1964 and 1966 — each offering two flavors of iconic tones. The 1964 side gives you a 25-watt cathode biased circuit, whereas the 1966 input features a 30-watt, fixed bias circuit. Sonically, the 1964 side is spongier and breaks up earlier, while the 1966 input gives you a tad more headroom and midrange beef. Additionally, you can toggle between selectable bias modes, yielding even more tones and textures.
B-15N FX Rack
The B-15N plug-in provides additional control over your sound through the inclusion of the Brainworx FX Rack. It features a Noise Gate to control low-end buzz, switchable high-pass and low-pass filters to provide even more tonal options, and a Power Soak circuit that allows you to dial in as much overdrive as you want, without having to crank the output gain.
Unison™ Technology for Apollo Interfaces
Harnessing UA’s groundbreaking Unison technology, the Ampeg B-15N plug-in gives you the impedance, gain staging, and circuit behaviors that have contributed to making this iconic bass combo one of the most recorded bass amps in history.

Yes. Nice job on this one, UA. Especially like all the microphone positions with and without EQ and great microphones. Inspirational bass sounds going in with UNISON and/or in a mix.続きを読む

well done once again!
This plugin, like many other UAD-Sim's just doesn't do it for me
- Lack of that "something"
- I cannot load my own IR's
- There is definitely something that I am not getting which I do get from a certain $12 competitor (I don't work for the competitor)
- The bass is just the same, there really is not much of the magic that UAD seem to achieve with other things such as Comps, Strips
My personal opinion is I won't be buying another UAD amp sim until they truly do make something special. Otherwise, go for the $12 competition. These sims, all of them, really do not cut it in my opinion. Comparing with a $12 sim, NO WAY!
Sorry UAD but you are lacking something and it's looking more to be "hype" than quality.
Quite out of my mind about that thing.
tomorrow my pay check
tonight recorded a heck of a song with this piece.
typically something, like the bluesbreaker you wanna use on 44.1, you know: nothing too fiddly, straight vibes in the belly with a perfect mixdown from your daw of course (sd hd to write to).
If Robin Hood took the money back from the rich and returned it to the poor, UNIVERSAL AUDIO took ROCK back from the rich and returned it to the poor! (yeah, yeah UA, you may use that quote:))
No Buy - Sorry UAD
Ok, demo'd again after your speedy response.
- The sim doesn't add any actual real difference to the competition I've compared with
- The lack of custom IR loading is huge factor
- As much as it's modelling (at a reasonable price) an Ampeg B-15N I do not think when it's released natively there will be any difference whatsoever
What I'd like to see is;
A high quality, a real UAD specific, tailored exclusively forever to UAD that is, bass sim that allows Cab Lab 3 type IR loading. A very unique plugin yet modelled on a modern amp head and is Unison including the IRs!
Honestly guys, I have not bought a single new product and I'm not even going to demo unless it truly is unique to UAD. Otherwise, you do good plugs

Pre-amp for drums?
I love the sound of great music from the 60s and 70s so when I got the chance to get some of that tone, I took it. UA delivered again as expected, but what wasn't expected is what this amp does for your vocal chain when you have a vocalist with no lower register. Warm. Clean. Nice. How about on drums? Yep. Use it on kick with your D112 and see how excited you get.
This is one of those plug-ins that immediately grabs you and says, "You need this". I was working on a project and using bass guitar samples. I just wasn't feeling it. I decided to demo the Ampeg and was blown away. I use it on real bass now!!
Just Sound like til Real one. :-)

Best Bass Amp in the Box!
I'm into that groovy 60s/70s bass sound. And this one has all the warmth, punch and balls of that era. Thank you UA; it's my to go to bass amp sim!
Nice drive. Another great Ampeg Sim
Full disclosure: I've never used the real amp. I have, however, used the Ampeg SVT Pro quite often and I was impressed by the plug-in's accuracy. I wanted more drive for dirtier tones, so demo'ed this. I was impressed. I use it often. It's simple, but I've realized it can achieve so many tones. Experiment with the input jacks, bias, and especially the FX rack section with the cabinet and mic simulators and then you'll get a sense of its range. In the mix, it's got that depth I like in the SVT plugin that gives the bass a real amp feel.
Love it. For that portaflex kind of sound its the best I have found. Adds some air & space to my DI track.
automatically sits in the mix
If you are going for that classic B-15 sound or just looking to nail in where the bass sits in the mix, this is the plug in for you. I also have used it as a pre-amp for live rehearsal settings and it sounds fantastic and super fat. The wide range of cap options and bias control make this plug in very flexible.

In electronic music I always use it in a duplicate track of the bass. it's fantastic
Just what I neded
So, I just needed something to plug my bass and record without much finagling.
Bammmm! this is it. Choose from some great presets, adjust a bit of EQ and DONE. Boutique bass sound. Simple.
great bass amp
It has a brilliant sounds and interface.
Most useful bass amp simulator in the world.
The Ampeg B-15N was my first choice of the bass plugins. The modeling is Phenomenal! The only negative: The mic choices Will keep you busy for hours, ha! Change nothing! It's perfect! The fat sounds are truly fat, yet very clear and punchy. It's my "go to" bass plugin. The Apollo 8 interface and plugin libraries have elevated all my work to levels higher than I thought imaginable! UAD folks- Thank You for providing these wonderful products!
I have the vintage B15N and use it on all my bass recordings...this is the first amp simulator that i find great and will be used in my recording for sure! The plugin is punchy and warm. I have to admit that i acutally like it on guitar too. Very good plugin! No regrets with this one.
